According to a strategic planning presentation disclosed to investors earlier this month, Sega's free-to-play mobile RPG Chain Chronicles reaped over 7.3 billion yen (~$72 million USD) in sales for the company across iOS and Android in the nine months following its launch last July.

That's remarkable financial performance for a mobile game, and it helps explain why the company is planning to launch 30 new free-to-play titles in the current fiscal year.

At least two of those will be Chain Chronicle games, as the company plans to capitalize on game's success by releasing a sequel on mobile and developing the free-to-play PlayStation Vita game Chain Chronicle V based on the original mobile hit.
